[目的]验证472 g/L硝·精·莠SE对玉米田杂草的药效、杀草谱及对玉米的安全性。[方法]采用土壤喷雾、定期调查的方法进行田间药效试验。[结果]药剂472g/L硝·精·莠SE的杀草谱较广,包括一年生禾本科杂草及大部分阔叶杂草。施药后40d调查,其对各种杂草综合防效幅度为87.9%~99.5%。鲜质量防效达到94.5%~99.9%。[结论]玉米播后3~5 d,472g/L硝·精·莠SE其适宜使用剂量为2 832~3 186 ga.i./hm~2,对水750L土壤喷雾。

[Objective] The research aimed to verify the efficacy, insecticidal spectrum and safety of 472 g / L Nitroxtrin Atrase SE to corn weeds. [Method] The field efficacy test was conducted by soil spraying and regular investigation. [Result] The pesticide 472g / L Nitroxtrin Atrazine showed a broad spectrum of herbicidal activities, including annual gramineous weeds and most broadleaf weeds. 40d after application survey, the comprehensive control of various weeds range of 87.9% to 99.5%. Fresh quality control reached 94.5% ~ 99.9%. [Conclusion] The suitable dosage of 472g / L Nitroxtrin / Ammonium for maize was 3 ~ 5 d after sowing, and its suitable dosage was 2 832 ~ 3 186 ga.i./hm ~ 2.
